Frankly, don’t pay too much attention to the absolute ranking or even slight movement. Take advantage of BW’s rich, informative database and fantastic resources for applicants. Then choose what’s important to you and do your own ranking.

BW bases its rankings on employer and student surveys as well as school research output or “intellectual capital.” This year for the first time, in a nod to the economic crisis, it is also including a ranking based on ROI and years to recoup the MBA investment. Not surprisingly, European schools, which tend to be one-year programs, are at the top of the chart. More surprising: HBS ranks 50 out of 50 in this chart. I guess assumptions matter.
